A pair of shadowy, feathered wings extend from your back and create a wall of impersevablse dark. With you at the center of the wingspan, the wall runs up to 20 feet long and 5 feet high. The wall is completely opaque and lasts for the duration.

When the wall appears, each creature full obscured behind it gains advantage on saving throws against psychic attacks and spells. Note, spells must originate from a point on the opposite side of the wall in order to grant coverage/ break their line of sight.
